Definitions

  • the invention relates to a method for monitoring the running behavior and/or the condition and/or the loading of conveyor belts in belt conveyors that are in operation and can be loaded with bulk material.
  • Such monitoring involves, on the one hand, ensuring that the conveyor belt runs in a straight line and knowing the position of the bulk material on the conveyor belt and, on the other hand, monitoring the changing condition of the conveyor belt, for example through treading, due to the wear and tear on the conveyor belt that inevitably occurs over the period of operation of longitudinal cracks, transverse cracks or lateral edge tears in the belt.
  • knowledge of the particle size distribution in a bulk material forming the load on the conveyor belt may also be desirable.
  • the first step is to DE-A-42 40 094 a monitoring device is described that both the current current course of the conveyor belt with respect to the support frames of the belt conveyor as well as the exact position of the bulk material on the conveyor belt are to be determined.
  • this is intended to ensure timely recognition Misalignment of the conveyor belt can be recognized in order to avoid damage to the conveyor belt, and on the other hand, an even loading of the conveyor belt should be ensured, for example by a feed chute, in order, for example, to prevent wear of the conveyor belt due to uneven loading and / or contamination of the belt conveyor due to falling bulk material.
  • the known device consists of a light source that projects a strip of light onto the material flow, with an additional camera recording the upper edge profile of both the conveyor belt and the bulk material lying on it and then an assigned image evaluation unit analyzes the upper edge profile.
  • the image signals recorded by the camera are digitized so that each pixel can be assigned a gray tone or color.
  • Two consecutive images are subtracted, with delimiting image elements, such as side edges of the conveyor belt or loading limits of the bulk material support, being bundled into pixel-wide lines in a difference image captured in this way.
  • the most likely boundary lines are determined as edge lines of the conveyor belt and the bulk material lying on it and are used to determine the distance between the side edges of the conveyor belt and the support structure and to determine the respective distances between the belt belt edges and the edges of the bulk material.
  • the known device has the disadvantage that the device is designed to be very complex and is also extremely prone to failure.
  • the top edge of the load can only be determined inadequately.
  • the accuracy of the image capture also depends on the respective environmental conditions, such as dust content or moisture content in the ambient air, and in this respect the analysis using the image evaluation unit is subject to large sources of error.
  • an opto-electronic system with a camera is installed in an area in which there is no bulk material support, preferably in the area of a deflection drum of the belt conveyor, which is intended to optically detect damage to the surface of the conveyor belt.
  • a radar antenna combination is also preferably arranged in the area of the deflection drum and is aligned perpendicularly to the surface of the conveyor belt, which, in addition to the strength members vulcanized into the conveyor belt, detects metal particles vulcanized into the conveyor belt at intervals in the longitudinal and/or transverse direction.
  • the CN 204 124 749 U discloses a device for monitoring the running behavior and the condition of conveyor belts in belt conveyors that are in operation and can be loaded with bulk material, with at least one radar antenna combination consisting of at least one transmitting antenna and one receiving antenna and aligned with the conveyor belt being provided on the belt conveyor.
  • at least one radar antenna combination consisting of at least one transmitting antenna and one receiving antenna and aligned with the conveyor belt being provided on the belt conveyor.
  • An ultrasonic sensor is used for monitoring, although it is stated that a radar sensor can also be used.
  • CN 204 124 749 U discloses a method for monitoring the running behavior or the condition or loading of conveyor belts in belt conveyors that are in operation and can be loaded with a bulk material, wherein at least one radar antenna combination consisting of at least one transmitting antenna and one receiving antenna and aligned with the conveyor belt is provided on the belt conveyor, wherein at least one radar antenna combination is arranged laterally to the conveyor belt and the radar antenna combination arranged laterally to the conveyor belt periodically records the reflection of emitted radar beams through the side edge of the conveyor belt and transmits corresponding signals to a signal processing unit.
  • the US 2021/0286948 A1 discloses a device for monitoring the Condition of a conveyor belt of belt conveyors, for which at least one Radar antenna combination is arranged at a distance from the conveyor belt and is aligned with its opening angle perpendicular to the surface of the conveyor belt and periodically records the reflection of emitted radar beams on the one hand through the surface of the conveyor belt and on the other hand through reinforcements embedded in the conveyor belt and transmits corresponding signals to a signal processing unit.
  • This facility is also limited to monitoring the condition of the conveyor belt.
  • the invention is therefore based on the object of providing an improved method for monitoring the mentioned aspects of belt conveyors, the accuracy of which is largely independent of the prevailing environmental conditions and which works with robust, proven components.
  • the invention provides a method for monitoring unloaded conveyor belts or conveyor belts loaded with bulk material in belt conveyors, in which at least one first radar antenna combination consisting of at least one transmitting antenna and one receiving antenna and aligned with the conveyor belt is provided on the belt conveyor, the at least first radar antenna combination is arranged laterally to the conveyor belt and is aligned with its opening angle obliquely from above to the associated side edge of the conveyor belt and to at least part of the adjoining surface of the conveyor belt and periodically the reflection of emitted radar beams through the side edge of the conveyor belt and at the same time through the loading limit of one on the Conveyor belt picks up lying bulk material and transmits corresponding signals to a signal processing unit and in which the distance in the signal processing unit between the radar antenna combination arranged laterally to the conveyor belt and the side edge of the conveyor belt and the loading limit is determined and compared with a target value stored in the signal processing unit.
  • At least one second radar antenna combination can be arranged at a distance from the conveyor belt and aligned with its opening angle perpendicular to the surface of the conveyor belt and corresponding signals can also be transmitted to a signal processing unit, while the second radar antenna combination aligned with the surface of the conveyor belt periodically reflects the reflection of emitted radar beams on the one hand through the surface of the conveyor belt and on the other hand through reinforcements embedded in the conveyor belt and transmits corresponding signals to a signal processing unit.
  • the signal processing unit In the signal processing unit, analog/digital conversion of the received signals as well as mathematical signal processing and application-related data processing regarding the received signals take place; At the same time, the signal processing unit serves as an interface to an operator of the belt conveyor or a corresponding process control.
  • the invention has the advantage that the radar technology used equally for the different monitoring aspects itself generates the monitoring data directly.
  • the radar technology delivers reliable measured values due to the focused beam area and also works with very robust components that ensure that the radar technology functions reliably with sufficient accuracy under the often harsh operating conditions. In this respect, the inclusion of additional monitoring devices such as cameras, etc. is not necessary.
  • the radar antenna combination consists of a radar antenna with a transmitting function and a receiving function.
  • the first radar antenna combination preferably the second radar antenna combination
  • the first radar antenna combination can consist of separate transmitting and receiving antennas, with only one transmitting antenna and one receiving antenna initially being sufficient
  • the first radar antenna combination preferably the second radar antenna combination
  • the second radar antenna combination aligned with the surface of the conveyor belt could comprise a transmitting antenna and a plurality of receiving antennas distributed across the width of the conveyor belt.
  • the first radar antenna combination, preferably the second radar antenna combination consists of a plurality of transmitting antennas and a plurality of receiving antennas.
  • two external transmitting antennas and an appropriate number of receiving antennas could be arranged between them.
  • the invention is not limited to these exemplary embodiments, but includes any arrangement and assignment of transmitting and receiving antennas.
  • a coherent frequency-modulated signal source is used to generate the signals fed into the first radar antenna combination, preferably the second radar antenna combination, as corresponds to the known principle of a frequency-modulated continuous wave radar (FM-CW radar).
  • FM-CW radar frequency-modulated continuous wave radar
  • ultra-wideband radar technology is used to generate the signals.
  • the use of radar technology makes it possible to record the position of the lateral rubber edge of the belt, the reinforcements vulcanized into the belt and the surface of the bulk material lying on the belt in the form of peaks.
  • the accuracy of the separation of the detected peaks with regard to determining the running behavior and/or the belt condition and/or the load depends on the bandwidth of the radar signal used. In this respect, the largest possible bandwidth of more than 5 GHz, preferably more than 10 GHz, should be aimed for.
  • the inverse synthetic aperture radar (ISAR) principle is used to achieve a high resolution, in which, with stationary radar, the movement of the conveyor belt in its running direction as a third Dimension is included in the evaluation of the signals in the signal processing unit.
  • the illumination zones of the antenna lobes should at least overlap slightly. Measurements are digitally assembled in equidistant steps to obtain a subpixel resolution. This results in measurements that are close together at a high measurement rate and are only a few millimeters apart.
  • the surface of the conveyor belt possibly including its load, can be mapped much more precisely over the entire length of the conveyor belt.
  • the distance between the first radar antenna combination arranged laterally to the conveyor belt and the side edge of the and/or the loading limit is determined and compared with a target value stored in the signal processing unit.
  • first radar antenna combinations are arranged on both sides of the conveyor belt, aligned obliquely from above, and periodically detect signals and transmit them to the signal processing unit.
  • the accuracy of the position monitoring of the side edge of the conveyor belt and/or loading limit is advantageously more precise than 5 mm, preferably more precise than 1 mm.
  • the distance between the second radar antenna combination aligned with the surface of the conveyor belt and the surface of the conveyor belt as well as the distance between the second radar antenna combination and the reinforcement vulcanized into the conveyor belt are determined in the signal processing unit and the dimension the wear occurring on the surface of the conveyor belt due to the bulk material lying on it is determined from observing the respective difference between the determined distances.
  • the signals can be recorded with a measurement rate of greater than 50 Hz.
  • granulometry of the bulk material is carried out in the signal processing unit based on the signals reflected from the bulk material particles lying on the conveyor belt.
  • the first radar antenna combination is fixed by means of a holding device to be attached to a support frame of the belt conveyor, the holding device being set up for a height adjustment and an angular orientation of the first radar antenna combination that can be adjusted with respect to the vertical
  • a corresponding device can be designed in such a way that the second radar antenna combination or several second radar antenna combinations arranged next to one another and covering the width of the conveyor belt are installed in the area of a drive drum or deflection drum for the conveyor belt or . are.
  • the second radar antenna combination or a unit of several radar antenna combinations can be moved periodically across the width of the conveyor belt.
  • FIG. 1 Only partially visible representation of a belt conveyor 10 shows the part of a support frame 11 on which a garland of individual support rollers 12 is suspended, on which a conveyor belt 13 rests.
  • the conveyor belt 13 is loaded with a bulk material 14, the lateral loading limit 15 of the bulk material 14 not reaching the outer side edge 19 of the conveyor belt, but rather maintaining a distance therefrom.
  • a first radar antenna combination 17 consisting of at least one transmitting antenna and one receiving antenna is held, which is aligned with an opening angle 18 of the radar beams on the side edge 19 of the conveyor belt 13 in such a way that the opening angle 18 is oblique
  • the first radar antenna combination 17 looking from above onto the conveyor belt 13 detects the associated side edge 19 of the conveyor belt 13 and at least part of the adjoining surface of the conveyor belt 13 with a partial area of the bulk material 14 lying thereon and the associated loading limit 15.
  • the type of distance determination can be recognized by means of an assigned reflection curve 20 which represents the different signal intensity of the reflection of the radar beams emitted by the first radar antenna combination 17.
  • a first peak 21 of the reflection curve 20 shows the impact of the radar beams on the side edge of the outermost support roller 12, this first peak 21 not being taken into account when evaluating the reflection signals.
  • the second tip 22 indicates the position of the associated side edge 19 of the conveyor belt 13, from which the distance 24 between the first radar antenna combination 17 and the side edge 19 of the conveyor belt 13 can be determined.
  • the third tip 23 indicates the position of the loading limit 15 of the bulk material 14 lying on the conveyor belt 13, so that from the distance between the first radar antenna combination 17 and the third tip 23 or from the distance between the second tip 22 and the third tip 23 Distance 25 between the side edge 19 of the conveyor belt 13 and the loading limit 15 can be determined.
  • a second radar antenna combination 33 is arranged in the area of a deflection drum 30 for the conveyor belt 13 and is aligned perpendicular to the surface 31 of the conveyor belt 13 guided over the deflection drum 30.
  • the radar beams emitted by the second radar antenna combination 33 are reflected on the one hand by the surface 31 of the conveyor belt 13, so that a distance 34 between the surface 31 of the conveyor belt 13 and the second radar antenna combination 33 can be determined.
  • the emitted radar beams also penetrate into the material of the conveyor belt 13 and are reflected here by the strength members 32 vulcanized into the conveyor belt 13 over its width, so that a distance 35 between the strength members 32 and the second radar antenna combination 33 can also be determined. From the difference between these two distances 34 and 35, the material thickness of the material above the reinforcement 32 up to the surface 31 of the conveyor belt 13 carrying a bulk material can be determined. To the extent that changes in this distance difference are detected through continuous or periodic monitoring of the corresponding distance difference, these changes allow conclusions to be drawn about any progressive wear on the conveyor belt 13.
